System Information
Operating system and graphics card
Windows 8 64 bit, MSI GT70 (Nvidia GeForce GTX 875MX / 4GB GDDR5)

Blender Version
2.78c e92f235283

I'm trying to load a background environment texture and also an OSL script to generate the background. First I load the environment texture, then I select "Open Shading Language" and it crashes.

Steps:
1 Start Blender 2.78
2 Change to Cycles Render
3 In World, select Choose Nodes, which switches to Background
4 Click Color, then Environment Texture
5 Load my texture
6 Change my object view to Cycle Rendered
7 Go to Render panel, select Open Shading Language button

Image goes to checker boarded background. I can't unselect Open Shading Language button. I can't change view modes to wireframe. Blender stops responding.

I've noticed loading environment textures is incredibly slow with osl enabled, but it doesn't crash, just sits there for a while but eventually it'll get it together and starts rendering...

@quarkburger Please check whether Blender keeps working (which it seems to be doing), in the task manager e.g.

Also, please try the latest build from our buildbot, there has been a lot of changes since 2.78 ;)

You're right. It does take a loooong time to process environment textures with osl enabled. I tried this in the latest build of 2.78 btw. Are there plans to speed this up?

Thanks
